Detailed Description
The present application is further described with reference to the accompanying drawings and the detailed description, and it should be noted that, in the present application, the embodiments or technical features described below may be arbitrarily combined to form a new embodiment without conflict.
Referring to fig. 1, an embodiment of the present application provides an identity identification method, which includes steps S101 to S104.
Step S101: receiving portrait information of a user.
In particular, in applications of a scene such as live portrait recognition, the portrait information may be directly captured by a live portrait capture device, such as a camera. In other scenarios, such as office inquiry, the portrait information may be transmitted through other devices.
Step S102: and determining a database to which the portrait information belongs according to a preset mapping table.
Specifically, the preset mapping table may be a table that is set in advance and used for representing the correspondence between different portrait information and different databases. The present disclosure does not limit the specific form of the mapping table as long as the mapping table can represent the above correspondence.
Step S103: and controlling vein collection equipment to collect the vein image information of the user.
The heme of the red blood cells in the veins of the human body is the reducing heme of oxygen, and the reducing heme can absorb near infrared rays, so when the near infrared rays irradiate the human body, only the veins can be reflected weakly, and vein line images are formed. Medical research proves that the shape of human veins has uniqueness and stability, namely, vein images of each person are different, vein images of different parts of the same person are different, and in addition, the shape of veins of healthy adults does not change any more. Therefore, each user can be accurately distinguished by the vein identification information.
In one embodiment, the vein image information may be palm vein image information or finger vein image information, and the collection of the two kinds of vein image information is faster and more convenient, and only the user needs to stretch his hand.
Step S104: and identifying the vein image information in the database to which the vein image information belongs, and returning an identification result.
Specifically, the recognition result may be displayed through a display screen or other device, for example, when the recognition is successful, the personal information of the user is displayed, and when the recognition is failed, characters such as "recognition failed", "user does not exist" are displayed and a prompt is given.
In the steps of the embodiment of the application, different portrait information is attributed to different databases according to a preset mapping table, when one portrait information is received, the database to which the portrait information belongs is judged in advance, and after the database to which the portrait information of the user belongs is determined, the vein image information of the current user is identified only by using the information in the database, so that the data amount used in the identification process is reduced, and the identification speed is accelerated.
In one embodiment, the mapping table in step S102 includes a correspondence relationship between user data and the database number, wherein the user data includes one or more of age data, gender data, and body type data. For example, the mapping relationship in the mapping table may be: the database of the number 1 corresponds to the information data of the male under 18 years old; the information data of the women under 18 years old correspond to the database of the number 2; the information data of the males between 18 and 60 years old corresponds to the database of the number 3; the present disclosure does not specifically limit this mapping, and the above is merely an example.
Further, referring to fig. 2, step S102 further includes the steps of:
step S201: and analyzing the portrait information to obtain user data contained in the portrait information.
Specifically, for example, by using a portrait recognition technique, data such as the age, sex, and body type of the user is extracted from the portrait to form total data of the user.
Step S202: and acquiring the serial number of the database to which the portrait information belongs according to the user data and the mapping table.
And after analyzing the data of the age, the gender, the body type and the like of the user, acquiring the database number to which the information of the user belongs according to the corresponding relation of the mapping table.
Step S203: and determining a database corresponding to the database number as a database to which the portrait information belongs.
And then corresponds to the database according to the database number.
Therefore, the user data is obtained through the analysis of the portrait information, and the user data corresponds to the database number, so that the operation speed of determining the database to which the portrait information belongs can be improved.
Referring to fig. 3, step S202 further includes the steps of:
step S301: and when detecting the database corresponding to the user data, acquiring the database number of the corresponding database from the mapping table as the database number to which the portrait information belongs.
Step S302: and when the database corresponding to the user data cannot be detected, acquiring the database number of a data total database from the mapping table as the database number to which the portrait information belongs.
Specifically, the case where the database corresponding to the user data is not detected includes: a plurality of user data analyzed by one portrait information, and corresponding database numbers are not uniform; or the analyzed user data does not have a corresponding database number in the mapping table. At this time, the number of the data base may be corresponded to the user data in this case.
Therefore, the comprehensiveness of the used detection data under special conditions is ensured.
Referring to fig. 4, in one embodiment, the identification method further includes step S401.
Step S401: collecting user data and vein image information of registered users to form a data base, dividing the data base into a plurality of databases according to the user data, wherein the user data comprises user identification.
Specifically, before receiving portrait information, user data, user identification and vein image information of registered users are collected to form a data base, and then the data base is divided into a plurality of databases according to the corresponding relation of the mapping table, and the databases are numbered. The user identification may be the name, identification number, etc. of the user.
This further accelerates the recognition speed.
Referring to fig. 5, in one embodiment, the identification method further includes step S501 and step S502.
Step S501: and when the identification result is successful, acquiring the user identification corresponding to the vein image information.
Step S502: and when the identification result is identification failure, prompting the user of the identification failure.
Specifically, when the vein image information is successfully obtained, the user identifier corresponding to the vein image information, that is, the information such as the name and the identification number of the user, is obtained from the corresponding database and is displayed on the display. When the identification fails, a failure result can be displayed on the display, and the user information can be prompted to be input.
Therefore, the final recognition result can be more clear and convenient to view.
In conclusion, the identity recognition method provided by the application reduces the data amount used for recognition and accelerates the recognition speed.
